Perhaps a silly question, but the subject says it all.
Output example (as root):
truss: can not attach to target process: Invalid argument
on: FreeBSD freebsd-virtual 11.1-RELEASE-p8 FreeBSD 11.1-RELEASE-p8 #0: Tue Mar 13 17:07:05 UTC 2018 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64
Yet, I can do it on Solaris. Not sure about Linux, but that's irrelevant.
Cheers,
Mark
